"The challenge now is for scientists to take the results of one ride through
Titan's atmosphere - 'this grand descent into the unknown,' in Dr.
Southwood's words - and pictures of its surface and see if the moon is, as

chemistry indeed similar to conditions that may well have existed on Earth
in the early solar system? If so, what does that reveal about the chemistry
of the origin of life?"
